ExcelMcp 1.10.1

What's New

Patch Changes

• #740 59ebf29 Thanks @sbroenne! - Fix conditionalformat add throwing on borderStyle/borderColor (#737). Writing border formatting on a conditional-format rule threw COMException: Unable to set the LineStyle property of the Border class. Root cause: FormatCondition.Borders is a 4-item collection indexed 1-4 (left/top/bottom/right), unlike Range.Borders which uses the xlEdgeLeft/Top/Bottom/Right constants (7-10) — writing (and reading) via those out-of-range indices silently returned an unbound placeholder that threw on write and reported blank values on read. Both the write path (add) and the read path (list-rules/list-worksheet-rules) now use the correct 1-4 indices, so border style and color round-trip correctly.

• 352b1da Thanks @github-actions[bot]! - Release automation: reliably commit the changelog back to main. The post-release step now pushes the compiled CHANGELOG.md update directly to main using an admin RELEASE_PAT, instead of opening a chore/changelog-vX PR. On this user-owned repo the GitHub Actions bot can't be a branch-protection bypass actor, so that PR could never satisfy the required status checks and piled up open — leaving several releases with a stale/missing CHANGELOG on main. The direct push (as a ruleset bypass actor) removes the stuck-PR failure mode entirely.
